Ановуляция является широко распространённой причиной женского бесплодия. Сигнальные пути, опосредованные рецепторами фолликулостимулирующего и лютеинизирующего гормонов, имеют важное значение для успешной реализации репродуктивной функции у женщин.</p></sec><sec><title>Цель</title><p>Цель: изучение вклада межгенных взаимодействий генетических вариантов FSHR rs6166 и LHCGR rs2293275 в патогенез ановуляции.</p></sec><sec><title>Методы</title><p>Методы. В исследование включены 208 женщин из бесплодных пар, проходивших процедуру лечения бесплодия с применением вспомогательных репродуктивных технологий в Центре репродукции человека и ЭКО г. Ростова-на-Дону, в том числе женщины с ановуляцией и нормально овулирующие женщины с трубным и мужским фактором. Женщины со сниженным уровнем ФСГ и/ или АМГ в сыворотке были исключены из исследования.</p></sec><sec><title>Результаты</title><p>Результаты. Распределение частот генотипов варианта FSHR rs6166 составило: AA (40%), AG (43%), GG (17%). Распределение частот генотипов варианта LHCGR rs2293275 составило: AA (9%), AG (52%), GG (39%). В настоящем исследовании выявлена двухлокусная комбинация FSHR rs6166 AG / LHCGR rs2293275 GG, ассоциированная с повышенным риском ановуляции (OR (95% CI) = 2,43 (1,48-4,01), p&lt;0,001). Кроме того, среди женщин с генотипом LHCGR rs2293275 AA не было ни одной с ановуляцией в анамнезе. Настоящее исследование также выявило различия среди женщин c комбинированным генотипом риска rs6166 AG / rs2293275 GG: у ановулирующих женщин наблюдалось повышение уровня АМГ, соотношения ЛГ/ФСГ и количества антральных фолликулов, а также снижение уровня ФСГ по сравнению с нормально овулирующими женщинами. Заключение. Настоящее исследование предполагает, что варианты FSHR rs6166 и LHCGR rs2293275 являются хорошими кандидатами для ассоциативных исследований и могут обеспечить эффективную модель для прогнозирования риска ановуляции.&gt;&lt;0,001).

Anovulation is a common cause of female infertility. Signal transduction by follicle-stimulating and luteinizing hormones receptors is substantial for the successful reproduction.</p></sec><sec><title>Aim</title><p>Aim: to study the contribution of intergenic interactions of FSHR rs6166 and LHCGR rs2293275 candidate gene variants to the development of anovulation.</p></sec><sec><title>Methods</title><p>Methods. The present study included 208 women from infertile couples who underwent assisted reproductive technologies, including women with anovulation and normally ovulating women with tubal and/or male factor. Women with reduced FSH and/or AMH serum levels were excluded from the study.</p></sec><sec><title>Results</title><p>Results. The genotypes frequency distribution for FSHR rs6166 and LHCGR rs2293275 gene variants was AA (40%), AG (43%), GG (17%), and AA (9%), AG (52%), GG (39%), respectively. The present study revealed the two-locus FSHR rs6166 AG / LHCGR rs2293275 GG combination associated with the increased risk of anovulation (OR (95% CI) = 2.43 (1.48-4.01), p&lt;0.001) In addition, among women carried genotype LHCGR rs2293275 AA, none experienced anovulation. The present study also revealed differences among women carrying the risk genotype. Anovulatory women with rs6166 AG / rs2293275 GG combined genotype had an increased AMH level, AFC and LH/FSH ratio and a decreased FSH level, compared to normally ovulating women with the same genotype of risk.</p></sec><sec><title>Conclusion</title><p>Conclusion. Present study proposes that FSHR rs6166 and LHCGR rs2293275 variants are good candidate markers for association studies, and together may provide an effective model for predicting the risk of anovulation.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>FSHR rs6166</kwd><kwd>LHCGR rs2293275</kwd><kwd>ановуляция</kwd><kwd>рецептор ФСГ</kwd><kwd>рецептор ЛГ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>FSHR rs6166</kwd><kwd>LHCGR rs2293275</kwd><kwd>anovulation</kwd><kwd>FSH receptor</kwd><kwd>LH receptor</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Российского научного фонда, проект № 23-15-00464.</funding-statement><funding-statement xml:lang="en">This study was funded by the Russian Science Foundation, project No. 23-15-00464.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Hamilton-Fairley D., Taylor A.
